“…The recorded values for Spadona leaf chemical composition, except for ADL, are quite similar to those reported by Sitzia et al (2006) and Di Grigoli et al (2012) for the same chicory cultivar grown in different grazing experiments in Sardinia and Sicily (Italy), respectively. The overall mean values obtained in our quality evaluations were consistent with the values reported for forage chicory quality in Turkey by Ozturk et al (2006).…”

“…Therefore, frequent grazing has been proposed to produce a high proportion of leaves, up to 78% of the total aboveground biomass (Li et al, 1997). Ozturk et al (2006) studied the evolution of the nutritive value of wild chicory forage, harvested at different maturity stages in Turkey, and demonstrated that chicory should be harvested at the vegetative stage to obtain higher quality forage. Sulas et al (2007) studied wild chicory plants from Sardinia and found that local populations of forage chicory can represent a valuable opportunity for semiarid environments under rainfed conditions.…”

Knowledge about the forage yield potential and bioactive compound contents of Mediterranean natural populations of chicory is still scarce, even though it could be very helpful in view of the exploitation of the feeding value of local chicory germplasm for ruminants. Dry matter yield, chemical composition, antioxidant capacity, total polyphenols, flavonoids, and condensed tannins content were determined in 7 natural populations of Mediterranean wild chicory and, as a comparison, in the chicory commercial variety Spadona. Original seed was collected in different pastureland areas of Sardinia (Italy) and plants were grown in North Sardinia. Statistically significant differences were found in the leaf dry matter yield, ranging from 1.3 to 3.8 t ha -1 , and were not found in protein and fiber contents. The local populations were comparable to the commercial variety; however, the antioxidant activities, detected by means of 2 in vitro assays, significantly differed between populations. Among bioactive compounds, total flavonoids ranged from 27 to 37 g catechin equivalent kg -1 dry weight and statistically significant differences were also found in total polyphenol content and nontannic polyphenols; condensed tannins were not detected. Considering the importance of some bioactive compounds for the enhancement of animal nutrition and welfare, the exploitation of variability in bioactive compound content and antioxidant capacity of the chicory natural populations can be important for a more complete valorization of its Mediterranean germplasm.

In this study, in vitro gas production values (hour/ml) of standard, alfalfa and corn plants at 3, 6, 9, 12, 24, 36, 48, 72 and 96 hours in Kahramanmaras Sutcu Imam University Animal Science Department Feeds and Animal Nutrition Laboratory. ) used cubic piecewise regression, Richard, Logistics, Gamma, Gompertz, Orscov, Sigmoaidal and Quadratic Piecewise Regression models were used. In the modeling study, mean squares of error, determination coefficient, Akaike information criterion and Durbin-Watson autocorrelation values were taken into account for each model of in vitro gas production values. As a result of the study, it was concluded that Logistic and Gompertz models had the best results in corn and alfalfa, standard, while the Gamma model had the worst results in all feeds in terms of the comparison criteria, mean squares of error, coefficient of determination, Akaike information criterion and Durbin-Watson Autocorrelation values.
